On a Friday night in Paraguay, Victor, a seventeen-year-old who makes a meager living making deliveries within a market by pushing a wheelbarrow, is desperate to make some cash when he gets an unusual proposal: to carry seven boxes of unknown contents in exchange for a torn half of a US hundred dollar bill. The other half is promised to him when he finished the job, which at first appears easy: he simply has to cross the eight blocks of the market. But when other carters are willing to escort the goods for a pittance of the profits, a chase in the dark, secret corridors of the market break out, with both Victor and his pursuers becoming accomplices in a crime about which they know nothing: not the cause, not the victim, not the victimizer, and not the boxes' contents.
